Hello,
I’am new at the company i am working for and not very familiar with Zammad, now i have to update our Zammad VM but did not sure about the right order. And have the fear that elastic search will cause the most problems during the update.
Basically i have the following system:
- Debain Buster (latest patches installed)
- Zammad 6.1.0-1701845240.5a81e629.buster (Package installation)
- Elastic Search 6.8.23 (Package installation)
I like to update:
- Debian Buster to Bullseye
- Zammad 6.1 to 6.2 including latest elastic search without breaking the Database
In which order i should do the updates and what steps i should care of not destroy any depencies?
I am at beginners level in Linux, so sorry for my question it is hard to understand all the different Manuals and sort the steps in the right order.
the good thing, since it is a vm and i’ve cloned the production system i have the magic of snapshots 
if things are going wrong… and there will…
Kind regards,
